In C# - Provide code samples for the following: Declare a two-dimensional array of integers names intArray17. Create a loop to calculate the sum of every element in the first column. Create a loop to calculate the sum of every element in the array.

Expert Solution

Please give the thumbs up, if it is helpful for you!!. Let me know if you have any doubts.

using System;

public class Test
{
public static void Main()
{
int[,] intArray17 = new int[4, 2] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } };
int first_col_sum=0;
int total_sum=0;
for(int i = 0; i < 4; i++){
first_col_sum+=intArray17[i,0];
}
Console.WriteLine("sum of every element in the first column: "+first_col_sum);

for(int i = 0; i < 4; i++){
for(int j=0;j<2;j++){
total_sum+=intArray17[i,j];
}
}
Console.WriteLine("Sum of every element in the array: "+total_sum);

}
}

Create a two-dimensional array A using random integers from 1 to 10. Create a two-dimensional array B using random integers from -10 to 0.

This program is for C.Create a two-dimensional array A using random integers from 1 to 10. Create a two-dimensional array B using random integers from -10 to 0. Combine the elements of A + B to create two- dimensional array C = A + B. Display array A, B and C to the screen for comparison. (Note a[0] + b[0] = c[0], a[1] + b[1] = c[1], etc.)
